Saving The Vicuña: The Political, Biophysical, And Cultural History Of Wild Animal Conservation In Peru, 1964–2000, Emily Wakild

History Faculty Publications and Presentations

This article examines national efforts to protect wildlife in the twentieth century. Its focus is the vicuña, a small llama-like species native to the Andes, which nearly went extinct due to the high economic value of its wool. Instead, the Peruvian national government—despite significant regime shifts—intervened to put in place and then perpetuate a series of conservation measures, including trade restrictions and a territorial reserve, that protected the population and allowed it to rebound. Using a combination of cultural, economic, political, and biological methods to understand the animals and people concerned about them, this article argues that conservation reoriented relationships …

Faculty, Staff and Students Publications

Inactivating mutations in the copper transporter Atp7b result in Wilson’s disease. The Atp7b−/− mouse develops hallmarks of Wilson’s disease. The activity of several nuclear receptors decreased in Atp7b−/− mice, and nuclear receptors are critical for maintaining metabolic homeostasis. Therefore, we anticipated that Atp7b−/− mice would exhibit altered progression of diet-induced obesity, fatty liver, and insulin resistance. Following 10 wk on a chow or Western-type diet (40% kcal fat), parameters of glucose and lipid homeostasis were measured. Hepatic metabolites were measured by liquid chromatography–mass spectrometry and correlated with transcriptomic data. Atp7b−/− mice fed a chow diet presented …

The Bioethical Significance Of “The Origin Of Man’S Ethical Behavior” (October 1941, Unpublished) By Ernest Everett Just And Hedwig Anna Schnetzler Just, Theodore Walker Jr.

Journal of the South Carolina Academy of Science

Abstract –

E. E. Just (1883-1941) is an acknowledged “pioneer” in cell biology, and he is perhaps the pioneer in study of egg cell fertilization. Here we discover that Just also made pioneering contributions to general biology and evolutionary bioethics.

Within Just’s published contributions to observational cell biology, there are substantial fragments of his theory of ethical behavior, a theory with roots in cell biology. In addition to such previously available fragments, Just’s fully developed theory is now available. This recently discovered unpublished book-length manuscript argues for the biological origins of ethical behavior (evolving from cells to humans, within a …

Classic Article: On The Oxidation Of Organic Matter In Marine Sediments By Bacteria, Selman A. Waksman, Margaret Hotchkiss

The Effects Of Postpartum Depression, Acculturative Stress, And Social Support On Mother-Infant Bonding Among U.S. Immigrant Women Of Arabic Descent, Darin Mansor Mathkor

Wayne State University Dissertations

Purpose and Background/Significance: The transition from “woman” to “mother” is a significant life event and can be extremely stressful when merged with the transition from ‘local’ to ‘immigrant’. The development of mother-infant bonding is considered a critical process in the postpartum period. Immigrant women have higher rates of PPD compared with women in their native countries. Among the general population, PPD is strongly associated with lower quality mother-infant bonding. Social support can play a central role in lowering the levels of PPD, and may contribute to higher quality of mother-infant bonding. Moreover, limited data suggests that acculturative stress is found …

Drug Discovery Targeting The Disorder-To-Order Transition Regions Through The Conformational Diversity Mimicking And Statistical Analysis, Insung Na, Sungwoo Choi, Seung Han Son, Vladimir N. Uversky, Chul Geun Kim

Molecular Medicine Faculty Publications

Intrinsically disordered proteins exist as highly dynamic conformational ensembles of diverse forms. However, the majority of virtual screening only focuses on proteins with defined structures. This means that computer-aided drug discovery is restricted. As a breakthrough, understanding the structural characteristics of intrinsically disordered proteins and its application can open the gate for unrestricted drug discovery. First, we segmented the target disorder-to-order transition region into a series of overlapping 20-amino-acid-long peptides. Folding prediction generated diverse conformations of these peptides. Next, we applied molecular docking, new evaluation score function, and statistical analysis. This approach successfully distinguished known compounds and their corresponding binding …
